  • The data set comprises time series of wave height and period data from in-situ wave recorders at fixed locations. Principal parameters are significant/characteristic wave height and mean zero crossing period - usually derived from the analysis of 20 or 30 minute recordings taken at intervals of the order of 3 hours. Data holdings include over 1500 recording months of data from some 60 sites across the continental shelf areas around the British Isles and the NE Atlantic between 1954 and 1995. Recording periods vary from 2 months at some sites to over 15 years. The longer series are noted here: Channel Lightvessel (49 54.4N, 002 53.7W; 01 Sep 1979 - 31 Dec 1985); Dowsing Lightvessel (53 34.0N, 000 50.2W; 01 May 1970 - 30 Apr 1971; 01 Nov 1975 - 30 Jun 1981; 01 Jan 1982 - 31 Dec 1982; 01 Jan 1984 - 31 Dec 1984); Ocean Weather Ship Lima (57 00.0N, 020 00.0W; 01 Jan 1975 - 31 Dec 1983); Saint Gowan Lightvessel (51 30.0N, 004 59.8W; 01 Aug 1975 - 31 Jul 1976; 01 Dec 1976 - 31 Dec 1983); Seven Stones Lightvessel (50 03.8N, 006 04.4W; 31 Jan 1962 - 31 Jan 1963; 01 Jan 1968 - 31 Dec 1969; 01 Jul 1971 - 30 Jun 1974; 01 Apr 1975 - 31 Dec 1985). The data originate primarily from UK and Irish laboratories and are managed by the British Oceanographic Data Centre. Data collection is ongoing at some sites (for example, Seven Stones Lighvessel) but these data are not managed by BODC. They are part of the Centre for Environment, Fisheries and Aquaculture Science (CEFAS) wavenet network.

  • Data from this project is a UK contribution to a US research cruise that aimed to examine the impact of wave breaking and bubble processes on air-sea gas exchange. Measurements were made of whitecap fraction, wave state, wave bubble statistics and bubble properties beneath breaking waves on the R/V Knorr KN213-3 cruise departing Nuuk, Greenland October 9, 2013 arriving at Woods Hole, USA on November 12, 2013. Instruments and platforms used included an 11 meter long free-floating spar buoy equipped with wave wires, a bubble camera, acoustic resonators, a Waverider buoy and ship measurements of aerosol fluxes. Data generation were funded by NERC parent grant NE/J020893/1 awarded to Professor Ian Brooks and associated child grants NE/J020540/1 and NE/J022373/2 awarded to Mr Robin Pascal and Dr Helen Czerski respectively.

  • The Monterey Bay Coordinated Canyon Experiment (CCE) collected physical oceanographic data in the Monterey Canyon study area, off the coast of Central California over an 18 month period between October 2015 and April 2017. This project was a long term effort to monitor turbidity currents using a variety of new instruments and technologies to assess movement of water and sediment, assess evolution and shape of the sea floor and monitor physical processes within flows at various spatial scales. Measurements were taken using an array of instruments which include: moorings; sediment traps, Acoustic Doppler Current Profilers (ADCP); transmissometers; vertical profilers; Benthic Instrument Nodes (BIN); Sediment Transport Event Detectors (STEDs); Benthic Event Detectors (BEDs); Autonomous Monitoring Transponder (AMT); wave sensors, autonomous underwater vehicles and wave gliders. The Monterey Bay Coordinated Canyon Experiment project was led by Monterey Bay Aquarium Institute (MBARI) in collaboration with researchers from the United States Geological Survey (USGS), Ocean University of China (OUC), National Oceanography Centre (NOC) Southampton and University of Hull, UK. MBARI are responsible for the long term data management of all datasets generated by the project. Datasets are hosted at the Marine Geoscience Data System (MGDS), a full data report is available from

  • This dataset consists of measurements of wave height, direction and frequency, bubble size distribution, Autoflux measurements of air-sea fluxes CO2, and WAVEX measurements of directional wave radar. Data were collected onboard the RRS James Clark Ross in the Weddell Sea during cruises in the 2010/2011, 2011/12 and 2012/13 field seasons. Meteorology data were collected using an aspirated psychrometer and temperature and humidity sensors mounted above the bridge of the ship. Wavex and Autoflux systems were run for the duration of each cruise. Bubble size distributions were measured with two acoustic resonators. These cruises formed the field component of NERC Discovery Science project "Waves, Aerosol and Gas Exchange Study (WAGES)”. The data were collected to measure the amount of aerosol at different sizes generated near the surface and transported upwards into the atmosphere, along with the wind speed, wave size and white-capping under a wide range of different conditions. The aim was to improve understanding of aerosol generation and ultimately the way in which clouds are represented within climate models. The Discovery Science project was composed of three Standard Grants. The lead grant, NE/G00353X/1, was held by the University of Leeds, School of Earth and Environment, with Professor Ian M. Brooks as principal investigator. The funding period for this grant was 01 August 2009 to 31 March 2014. Child grant NE/G003696/1 was held by the National Oceanography Centre, Department of Science and Technology and was led by Professor Meric Srokosz. The funding period for this grant was 01 September 2009 to 31 March 2014. The third grant was held under the title “pCO2 data collection on James Clark Ross in support of Autoflux” at the Plymouth Marine Laboratory. It was led by Professor Phillip D. Nightingale and was funded for the period covering 01 April 2010 to 31 March 2013. All data described have been received by BODC from the RRS James Clark Ross and will be processed and made available online in the future. Raw data are available on request.

  • This dataset comprises hydrographic and meteorological data transmitted in near real time from unmanned surface vehicles (USVs). Also included are hydrographic profiles through the water column obtained from submarine Slocum gliders, upon recovery. Data from these platforms have been converted into the international 'Everyone's Gliding Observatories (EGO)' exchange format. The dataset is supported by barotrophic tidal current imagery. Hydrographic data were obtained from two geographical regions. Firstly, from a transect extending from the Isles of Scilly out to the moored Carbon And Nutrient Dynamics and Fluxes Over Shelf Systems ('Candyfloss') Array in the Celtic Sea. Subsequently, a more localised survey was carried out in the English Channel, south of Plymouth. The tidal image data span the period 1st October to 21st November 2014 (15 minute intervals). Autonomous platforms were deployed between 1st and 26th October 2014 (Phase One, Celtic Sea), subsequently between 4th and 7th November 2014 (Phase Two, English Channel). Data were collected as part of Marine Autonomous Systems in Support of Marine Observations ('MASSMO'), contributing to the Exploring Ocean Fronts project. Tidal images are a product of Proudman Oceanographic Laboratory Coastal Ocean Modelling System (POLCOMS) simulation runs. MASSMO was carried out as a trial of new autonomous technologies and to collect scientific data, including observation of marine life. The dataset acquired provides valuable oceanographic and meteorological measurements including a traverse of an ocean front. MASSMO was a collaborative effort involving various UK laboratories and commercial organisations, coordinated by the National Oceanography Centre (NOC). This data archive consists of measurements made by wavegliders operated by NOC and the Centre for Environment, Fisheries and Aquaculture Science (Cefas), the MOST Autonaut and Slocum glider units 398 and 400, operated by NOC.

  • The dataset includes a wide range of physical, chemical and biological oceanographic parameters. Physical hydrographic measurements include temperature, salinity, optical backscatter, current velocities and turbulence, while biogeochemical measurements in the water column include dissolved oxygen, organic carbon and nitrogen, and nutrients. Biogeochemical parameters were also measured in sediment cores, while phytoplankton and zooplankton data were also collected. The marine data were supplemented by meteorological measurements including temperature, pressure, irradiance and wind. The experimental phase of the project was undertaken in the North Sea between 1998 and 1999, and data were collected at two contrasting sites: Northern North Sea (NNS, 59deg 20.0E, 1deg 00.0E) and Southern North Sea (SNS, 52deg 15.0N, 4deg 17.0E). At both locations measurements were concentrated at a central position with additional measurements being made to estimate horizontal gradients. Moored instruments were deployed at NNS from September - November 1998 and at SNS from March - May 1999. Each experiment was supported by intensive measurement series made from oceanographic ships and involving turbulence dissipation profiler, conductivity-temperature-depth (CTD) profilers, particle size profilers, optical profilers, benthic sampling and water bottle sampling. PROVESS is an interdisciplinary study of the vertical fluxes of properties through the water column and the surface and bottom boundary layers with the aim of improving understanding and quantification of vertical exchange processes in the water column. Scientists from 18 institutions distributed in 8 European countries participated in the fieldwork and modelling parts of the programme and was co-ordinated by John Howarth of the Proudman Oceanographic Laboratory. The British Oceanographic Data Centre (BODC) is responsible for assembling the data collected during the project into a comprehensive data set. The data has been organised onto a CD-ROM product available through BODC.

  • The data set comprises a diverse collection of physical, chemical and biological measurements, encompassing well over 1000 parameters. There are data from over 1000 conductivity-temperature-depth (CTD)/rosette stations, over 440 core profiles, over 180 sediment trap samples, over 140 net hauls and much, much more. The primary study area was a box extending to the base of the slope from Vigo to Cap Finistere. However, data are included from both further offshore (filament tracking) and from the Portuguese Margin. Measurements were taken from November 1996 to October 1999 during 33 cruise legs, involving research vessels from seven nations. Data were collected using a variety of equipment and techniques, including expendable bathythermographs (XBTs), turbulence probes, CTDs and oceanographic undulators with auxiliary sensors. These hydrographic profiles were accompanied by net hauls, plankton recorder deployments, sediment cores and a comprehensive water sampling programmes during which a wide variety of chemical and biological parameters were measured. The station data were supplemented by underway measurements of oceanographic and meteorological properties. Results from production and phosphate uptake experiments are also included in the dataset, as are bathymetric data from multibeam (swath) surveys, coastal upwelling measurements and data from moored instruments and benthic landers. The dataset also includes imagery from satellites, seabed photography and X-ray photographs of core samples. The aim of the project was study biogeochemical processes at the shelf break and to quantify the fluxes of material between the shelf and the open ocean. The project brought together over 100 scientists from 40 research centres and universities throughout Europe. The British Oceanographic Data Centre (BODC) is assembling the data sets collected during OMEX II into its project database system and the data set is also available on CD-ROM.

  • The UK Surface Ocean-Lower Atmosphere Study (UK SOLAS) marine fieldwork data set comprises all data, marine or otherwise, collected during sea-going activities. The fieldwork included eight dedicated research cruises in the eastern North Atlantic Ocean, spanning the period 2006-2008. These cross-disciplinary missions resulted in a diverse data catalogue. This includes meteorology (3-D wind speed and direction, total irradiance, Photosynthetically Active Radiation/PAR, air temperature, atmospheric pressure, humidity, aerosol optical thickness); atmospheric composition (carbon dioxide concentration, aerosol particle counts and size spectra, chemical analyses of aerosol particle composition, cloud condensation nuclei/CCN, concentrations of pollutants such as black carbon, concentrations of free radical species such as iodine monoxide and nitrate radicals); chemical and energy-fluxes across the air-sea boundary (dust deposition rates, oxygen and nitrogen fluxes, carbon dioxide fluxes, sensible heat fluxes, latent heat fluxes, momentum fluxes); biological, chemical and physical properties and processes in the sea surface micro-layer (chlorophyll concentration, bacterial production, phytoplankton and bacterial speciation, concentrations of biogenic trace compounds such as halocarbons, nitrous oxide, dimethyl sulphide/DMS and alcohols, surfactant concentrations, halogen concentrations such as iodine, iodide and iodate); biological, chemical and photochemical properties and processes in the ocean subsurface (primary productivity, trace gas production, plankton community composition, nutrient concentration, concentrations of trace metals such as iron, aluminium, manganese, magnesium and cobalt, ligand and complex metal chemistry parameters such as heme, dust dissolution, salinity, temperature, amino acids and urea, carbonate system chemistry including alkalinity); and sea-state physics (breaking waves, wave slope, whitecaps, bubble size spectra, aerosol formation, subsurface acoustics). Additionally, time series of air-sea fluxes were measured from the Norwegian weather ship, Polarfront, between 2006 and 2009. UK SOLAS scientists also participated in the Bergen Mesocosm experiment during 2008. This simulated gas exchanges and biological, chemical and photochemical properties and processes in the sea surface micro-layer under controlled conditions. The study united atmospheric and marine scientists from institutions across the UK and international collaborators. The UK SOLAS data set was intended to advance understanding of the mutual interactions between the atmosphere and the oceans, especially the chemical exchanges that affect ocean productivity, atmospheric composition and climate. It was funded by the UK Natural Environment Research Council, as the UK's contribution to the international Surface Ocean-Lower Atmosphere Study (SOLAS). The data are held at the British Oceanographic Data Centre (BODC) and have been incorporated into the National Oceanographic Database (NODB). Data collected from non-ship based activities, for example land-based atmospheric data and data resulting from campaigns using the Facility for Airborne Atmospheric Measurements (FAAM) aircraft are held at the British Atmospheric Data Centre (BADC).
